Work to upgrade an electricity network, which services more than 15,000 customers, will start this week.
Electricity North West will begin its £289,000 ' Walkden project ' on Wednesday (December 2), which will see 600m of underground electricity cables replaced with 700m of new cable.
The old cables were initially installed in the 1950s and Electricity North West said the work is being carried out as "the need for electricity is only increasing".
Ian Baldock, Electricity North West’s project manager for the work in Walkden, said: "The service we provide is critical and, as key workers providing a vital service, its crucial we continue to improve the power network.
"The need for electricity is only increasing, more and more people are reliant on it and that’s why we’re proactively replacing the underground cables which were first installed in the 1950s."
The work will start in Mountain Street, before moving into Bolton Road and eventually Hill Top Road.
Work is expected to last for three months and roadworks will be in place, while the improvements are carried out.
Mr Baldock added: "When major work like this is carried out, roads need to be dug up to lay new cables and it isn’t an easy time for commuters or residents. But, as always, we will do our best to keep disruption to a minimum and I want to thank the residents of Walkden in advance for their understanding and co-operation."
Residents will be warned of any works taking place and the project is expected to be completed in March.
